Sorry having some trouble....
Something to worry about?
Hi all, this is one of my 3 week old WW. I’m noticing a bit of yellowing between the leaf veins. They’re in ffof and under a 250w mh light. Think it’s anything to be concerned about? I havnt been adding any nutes at all,just water.
If it’s calmag deficient can I fix it through watering with a Cal mag solution or does it need to be a foliar application.
